.invented a certain new and useful Electrical Coupling, of which the followingjis a specification.

Our invention has 'for its object the production. of an electrical coupling or line tapper, which is particularly simple in con struction and highly etlicicnt in use; and itI consists in the combinations and construetions hereinafter set 'forth and claimed.

ln describing this invention, reference is had to the accon'ipanying drawing, in which like characters designate correspondii'ig parts in all the views.

Figure 1 is a longitudinal sectional view, partly in elevation, of this coupling or line tapper, contiguous portions of conductors connected thereby being also shown.. Fig. a longitudinal sectional view taken on line .fir-A., Fig. 1, parts being omitted. Fig. 3 is an elevatiompartly in section, oi the coupling, the movable division of the sleeve or band .member and the separable section of the stem being shown as swung outwardly to permit the insertion of a conductor.

1 is the threaded stem of the body of the tiansversely' extending sleeve or band member located atl one end of the stem and adapted to receive a conductor 4, the division 2 being lixed to the stem, and the'division 3 being hinged at 5 to the division 2. The coupling is also provided with means at the other end ot'. its stem Vfor engaging a` second conductor 6, said means including a contractile sleeve 7 arranged in an axial.

socket. 8 opening through the end of the threaded stem 1 opposite tothe sleeve or band member, the sleeve 7 having a conical periphery which engagesl a complemental circumferential wall of the socket 8. The sleeve 7 is 'forced into the socket 8 by means ot' a nut. or internally vthreaded' sleeve 9 `turr'iing on said other end of the'stem and having an internal tiange 10 which engages the outer end of the sleeve 7 and thereby forces said sleeve into the conical socket 8 and compresses the saine upon the con- I duct-or G.

The portions of the stem 1 adjoining the sleeve or band member includetwo partcylindrical sections 11 and 12 complemental 'PATENT DOSSE-T,OF SYBACUSE, NEWT YORK, ASSGNUR OF SYRCUSE, NEW YORK. A CORPOR-A'I'IN G2 NEW' 53p@cftation of Letters Patent.

The fixed section ot' the stem is formed with a part-cylindrical portion 13 concentric with, but of opposite curvature to, and of less radius than, the threaded surface of said iixcd section 11, and the separable section 12 is formed with a recess 1-1- fitting said part-cylindrical portion 13.

15 is a lengthwise axial passage in the stem 1 communicating at its ends respectively with the bore of thc sleeve member and the socket- 8, and preferably formed at its end adjacent Athe socket 8 with an annular enlargement and with an annular shoulder 1G, the shoulder 16 being here shown as the end wall of said enlargement.

17 is the head. oit a l'novable clamping element which also includes a sha-nk 18, the head 17 being located within the bore of the sleeve member and provided with an arcuate face 1S) for engaging the conductor et, and the shank 18 extending within the passage 15 and slidably iitting the portion thereof of reduced size. The free end of the shank is provided with an axial threaded socket Q0 which receives a screw 21 having its head engaged with the end face ol the shank and projecting laterally therefrom for Ytoi-ming an enlargement or shoulder 22 on the shank for engaging the shoulder 1G and limiting the movement of the shank out of the passage 15, said coacting shoulders 1G and 18 being external to the sleeve member. Access to this screw 21 is afforded through the socket -8 and the enlarged end of the sleeve member, and project laterally on opposite sides of said stem and the sections 11 and 12 thereof. l

25 isa nut turning on the threaded stem 1 and the sectionsfll and l2 thereof against the projecting portions ,ot the lugs 23 for iorcing the clamping element axially of the stem and thus firmly clamping the conductor el in the sleeve member.
